Ruby on Rails无法找到控制器的操作

Question

我的rails应用说：

The action 'myjson' could not be found for UsersController

我整天都在阅读其他帖子，看起来这主要是由于缺少结局或其他原因造成的。但我真的不认为这是因为我真的试图查找它并找不到任何东西。所以我转向你寻求帮助。这是我的控制器代码：

class UsersController < ApplicationController

 helper_method :sort_column, :sort_direction  #method in helpers to sort
 before_filter :signed_in_user, only: [:edit, :update, :destroy] 
 before_filter :correct_user,   only: [:edit, :update]
 before_filter :admin_user,     only: [:destroy]

 def index
  @user = current_user
  @usersall = User.all
  @users =User.order(sort_column + " " + sort_direction).paginate(:per_page => 10, :page => params[:page])
  @rank = User.select("users.name, sum(credits.score) AS rank").joins(:credits).group("credits.user_id").all
end

 def destroy
  User.find(params[:id]).destroy
  flash[:success] = "User destroyed."
  redirect_to users_path
 end

 def create

   if User.exists?(:email => params[:user][:email])
    flash.now[:error] = "A user with this email already exists"
    render :action => :new, :layout => 'signin-layout.html.erb'
   elsif params[:user][:password] != params[:user][:password_confirmation]
    flash.now[:error] = "The passwords do not match. Try again"
    render :action => :new, :layout => 'signin-layout.html.erb'
   elsif params[:user][:email] !~ /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
    flash.now[:error] = "Invalid email"
    render :action => :new, :layout => 'signin-layout.html.erb'
   elsif params[:user][:name] == nil
    flash.now[:error] = "The name field cannot be empty"
    render :action => :new, :layout => 'signin-layout.html.erb'
   elsif params[:user][:password].length < 6
    flash.now[:error] = "Password is too short (minimal length: 6)"
    render :action => :new, :layout => 'signin-layout.html.erb'
   else
    @user = User.new(params[:user])
    @user.save
    redirect_to @user
   end
end

def show
  @user = User.find(params[:id])
  render :layout => 'user-layout.html.erb' #use a special layout
end

def edit
  render :layout => 'user-layout.html.erb' #use a special layout
end

def update
  if User.exists?(:email => params[:user][:email]) && params[:user][:email] != @user.email
    flash.now[:error] = "A user with this email already exists"
    render :action => :new, :layout => 'signin-layout.html.erb'
  elsif params[:user][:new_password] != params[:user][:password_confirmation]
    flash.now[:error] = "The passwords do not match. Try again"
    render :action => :new, :layout => 'signin-layout.html.erb'
  elsif params[:user][:email] !~ /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
    flash.now[:error] = "Invalid email"
    render :action => :new, :layout => 'signin-layout.html.erb'
  elsif params[:user][:name] == nil
    flash.now[:error] = "The name field cannot be empty"
    render :action => :new, :layout => 'signin-layout.html.erb'
  elsif !@user.authenticate(params[:user][:password])
    flash.now[:error] = "Entered password doesn't match with the one previously saved"
    render :action => :new, :layout => 'signin-layout.html.erb'
  else

    @user.update_attribute(:name, params[:user][:name])
    @user.update_attribute(:email, params[:user][:email])

    if params[:user][:new_password] == params[:user][:password_confirmation] && params[:user][:new_password].length > 6
    @user.update_attribute(:password, params[:user][:new_password])
  end

  sign_in @user
  redirect_to @user
 end
end


def upAdmin
  @user = User.find(params[:id])
  if @user.update_attribute(:admin,true)
    flash[:success] = "Profile updated, welcome to the new admin"
    redirect_to @user
  else
    flash[:error] = "Profile can't be upgraded to admin !'"
    redirect_to @user
  end
end

def downAdmin
  @user = User.find(params[:id])
  if @user.update_attribute(:admin,false)
    flash[:success] = "Profile updated, bye to the old admin"
    redirect_to @user
  else
    flash[:error] = "Profile can't be updated !'"
    redirect_to @user
  end
end

def myteam
  @user = User.find(params[:id])
  if @user.team_id != nil
    @team = Team.find @user.team_id
  end
  render layout: 'user-layout.html.erb'
end

def myjson
  render :layout => 'myjson.html.erb'
end

def myprojects
  @user = User.find(params[:id])
  render layout: 'user-layout.html.erb'
end

def mydevices
  @user = User.find(params[:id])
  render layout: 'user-layout.html.erb'
end

def mypins
  @user = User.find(params[:id])
  render layout: 'user-layout.html.erb'
end

private

def sort_column
  User.column_names.include?(params[:sort]) ? params[:sort] : "name"
end

def sort_direction
  %w[asc desc].include?(params[:direction]) ? params[:direction] : "asc"
end

def signed_in_user
  redirect_to signin_path, notice: "Please sign in." unless signed_in?
end

def correct_user
  @user = User.find(params[:id])
  redirect_to(root_path) unless (current_user?(@user) || current_user.admin?)
end

def admin_user
  redirect_to(root_path) unless current_user.admin?
end

end

所以我希望我错过了它并没有什么严重的。以防万一这是我的routes.rb用户：

get "users/new"

  resources :users do
    member do
      get 'myteam'
      get 'myprojects'
      get 'mydevices'
      get 'mypins'
      get 'upAdmin'
      get 'downAdmin'
      get 'myjson'
    end
  end
